Blepharitis is a common and chronic inflammation of the eyelids caused by a problem of the lid oil glands,  bacterial infection or skin condition like rosacea. The eyelid margins are usually red rimmed. There is usually crusting around the base of the lashes which some refer to as “granulated eyelids.” Often people with blepharitis have more frequent oil gland inflammation and develop a chalazion, or stye. But there are many Blepharitis treatments available.
